It is better than I expected, you are full of surprises.

I will make up an interface board for the EWG/HFS4's grey harness. I will use the White, brown and black wire. I believe those wires are available.

I will also send you a T-Map harness so we can that too. Please pm me your address,

[mdhollis]

Haha that's great, I try!

Yeah the white, black and brown are def open. Pm sent...

Will it be a problem if I have the tmap looped through the jb4 as well?


Not sure, we shall see, it always possible to do it on the output side of the JB to avoid any signal clash.

Oh Richard one more thing... I have a hell of a time soldering those little pins on the board. Can you take care of whatever needs to be soldered? Using 7 jets, 2.5 bar tmap

We can always wire it after the JB. It is only a push button for a second to drop boost.

You don't need to do any soldering.

Post a picture of your set up.[/quote]

Ok great Rich. Yeah I don't mind testing with the jb...

I believe the board is set up fine for the application I am installing right now, just wasn't sure exactly what you were sending me. If it was an additional control or a replacement hfs-4 controller....

Here is the pic of my board(v2 controller I bought in 2013, I ran on my old car):

All the wirings will be outside of the controller, there is no modification or soldering on the controller. I will be utilising the white, brown and black wire of the grey harness when done.

At this stage, no need to involve the HFS4 at all. It will be clear when you receive the bundle.
